The Columbia and Kootenay Railway (C&KR) was a historic railway operated by the Canadian Pacific Railway (CPR) in the West Kootenay region of British Columbia. This 25-mile (40 km) route, beside the unnavigable Kootenay River, linked Nelson on the west arm of Kootenay Lake with Robson at the confluence of the Kootenay River and the Columbia River near Castlegar.
